Great first issue. I especially like the dialog page in the back that explain all the teams, even if it wasn't part of the read!
Mr. Sinister is my favorite villain, but the everything Sinsiter part seemed a tad off to me. I prefer him with his Marauders. But still, he didn't disappoint. Whenever he's shown there's something big going on, and you can bet he's behind it. Sure enough here with the Celestial.
Colossus tapped into the Juggernaut power which is interesting, as he didn't in X-Men Vol 3 #20. But his little demonic sister was there to help him out. This issue mainly focuses on the "Extinction Team" and there battle against Sinister and the Celestial, but you do see some background characters. Sunspot (what I can only assume is him) looks a bit like Cannonball though.
Not a whole lot to really say, but it was a good book. A starter, but still plenty of action. Funny quote from Storm, and she makes a good point. Colossus, Magik, Magneto, Namor, Emma, Danger, and Cyclops have all been considered villains before. Storm and Hope are the only two to have never been, and yet that's the main team of X-Men. But who cares? They'll flow good together.
There of course can be the entire Cyclops/Emma/Namor thing, Colossus and Magik are related, Danger and Emma get along well, Magneto and Colossus have some past, Hope can pretty much tie in with any of them. It all fits to me, and I like it. On Wolverine's side, you have Beast with him, and that doesn't seem right to me, among other items..
A dialog picture in the back of the book further explains the different X-Men teams on Utopia. There's the X-Club team: Nemesis, Kavita, Jeffires, Danger; the "Security Recon" team of X-Men: Psylocke, Domino, Warpath, Jubilee; the "Street Team" of X-Men: Dazzler, Boom Boom, Lifeguard (whoa! they plan on showing her!!); the "Clean-Up" team (New Mutants): Dani Moonstar, Cypher, Warlock, Magma, Sunspot, X-Man; the "Generation Hope" team (Lights): Primal, Hope, Zero, Velocidad, Transonic, Pixie (don't really get why she gets to be a part of this tema and the other younger ones can't. guess she's just more popular); and the "Recruits": Prodigy, Cuckoos, Dust, Loa, Surge, Crosta, Martha. I'm a bit confused there though. I thought Dust, Crosta, Martha, and Loa were all with Wolverine...
I rather enjoyed this much so, especially for a first book-I'll go ahead and give it a 5 out of 5. My favorite "students" are basically Surge, Dust, Pixie, and Hellion, and Cyclops' team has three out of four. Not bad. Anyways, if you're a fan of X-Men and can't deicde which book to pick up-pick this one.
